ADJUSTABLE STRAP FOR ECCENTRICS.

SPECIFICATION forming part of Letters Patent No. 736,847, dated August,18, 1903.

Application filed May 2, 1903. Serial No. 155.361- (No model.)

To all whom, it may concern.-

Be it known that LWALTEE HARLING, a citizen of the United States,residing at Blaine,

in the county of Whatcom and State of Washington, have invented new anduseful Improvements in Adjustable Straps for Eccentrics, of which thefollowing is a specification.

My invention relates to new and useful improvements in adjustable strapsfor eccentries; and its object is to provide a simple and inexpensivedevice of this character which may be adjusted upon the eccentric totake up wear thereon without the necessity of first removing the strapfrom position upon the eccentric.

The invention consists in providing a strap formed of two substantiallysemicircular sections, each of which is provided with a groove and atongue at opposite sides, and the two sections are so located that thetongue of one section will engage the groove of the other section. Awedge of novel construction is arranged within each tongue and groovefor binding the two parts in proper relation to each other, andadjusting-screws are employed for moving the strap-sections into properposition.

The invention also consists in the further novel construction andcombination of parts hereinafter more fully described and claimed, andillustrated in the accompanying drawings, showing the preferred form ofmy invention, and in which Figure 1 is an elevation of an eccentricstrapconstructed in accordance with my invention. Fig. 2 is a section throughone side of the strap and the adjusting means employed in connectiontherewith. Fig. 3 is a section on line a: 00, Fig. 1. Figs. 4 and 5 aredetail views of the two sections of the strap; and Fig. 6 is a sectionthrough one end of the strap, showing the sections thereof secured bymeans of a modified form of wedge.

Referring to the figures by numerals of reference, 1 and 2 aresubstantially semicircular sections forming myimproved eccentric-strap,and an extension 3 is formedintegral with the section 2 and is keyed orotherwise secured to a rod 4. A tongue 5 extends forward from one end ofeach of the sections 1 and 2, and these tongues are adapted to beslidably mounted within rearwardly-extending arms 6, having longitudinalgrooves 7 therein. Inclined slots 8 are formed within the arms 6 andtongues 5 and are adapted to receive wedges of novel construction. Eachwedge is formed of two partst0 wit, a tapered plate 9, having alaterally-extending ear l0, and a block 11, having a threaded stem 12,which is adjustably mounted within said ear. It will be understood thatwhen a nut 13 is screwed upon stem 12 block 11 will be drawn toward ear10, and the distance between the outer faces of plate 9 and block 11will be increased, thereby imparting a longitudinal movement of thetongue 5, arranged within the arm 6, within which the wedge is seated.Adjusting-screws 14 may be arranged within the strap-sections at pointsadjacent to the tongues 5,and these screws are adapted to bear upon theopposite ends of said straps to space them from each other a desireddistance.

In Fig. 6 I have illustrated a modified form of wedge, in which theblock 15 is shown provided with grooves 16 for the reception of thewalls of slot 8 in arm 6. By employing a wedge-block of this characteran increased movement of the tongue 5 within arm 6 may be obtained. Asshown in Figs. 1 and 4, ringsection 1 may be provided with a suitableoilcup 17. To securea strap such as herein described in position upon aneccentric it is.

- When it is desired to take up wear upon either the eccentric or strapsections, it is merely necessary to unscrew the screws 14 and adjust theblocks 11 nearer the cars 10 on the tapered plates 9 until the tongues 5have been moved longitudinally within arms 6 for a suitable distance. Itwill be seen that the device is extremely simple and inexpensive inconstrue tion, and by the use thereof it is not neces sary to remove thestrap from the eccentric, as heretofore, when it is desired to adjust itupon the eccentric.

In the foregoing description I have shown the preferred form of myinvention; but I do not limit myself thereto, as I am aware thatmodifications may be made therein without departing from the spirit orsacrificing any of the advantages thereof, and I therefore reserve theright to make such changes as fairly fall within the scope of myinvention.

Having thus described the invention, what is claimed as new is 1. Aneccentric-strap formed of sections adapted to be placed at oppositesides of an eccentric, a Wedge for connecting the sections and adjustingthem upon an eccentric, and means for securing the sections in adjustedposition.

2. An eccentric-strap comprising sections adapted to be arranged atopposite sides of an eccentric, a tongue and an arm at opposite ends ofeach section, and means for adjustably securing the tongues and arms ofthe sections together.

3. In an eccentric-strap, the combination with sections adapted to beplaced at opposite sides of an eccentric; of a tongue and arm atopposite ends of each section of the strap, adjustable wedges connectingthe tongues and arms and adapted to adjustably secure the sectionstogether, and means for locking said sections in adjusted position.

4. An eccentric-strap consisting of two sections adapted to be placed atopposite sides of an eccentric, a grooved arm and a tongue at oppositeends of said section, said tongues being adapted to be seated within thegrooved arms, adjustable Wedges mounted within slots in the tongues andarms, and means for locking said tongues and arms in adjusted position.

5. An eccentric-strap formed of sections adapted to be placed atopposite sides of an eccentric, a grooved arm and a tongue at oppositeends of each section, an adjustable wedge in slots in each arm andtongue, and an adjusting-screw within each section and adapted to bearupon the opposite section.

6. An eccentric-strap formed of sections adapted to be placed atopposite sides of an eccentric, a longitudinally-grooved arm and atongue at opposite ends of each section, said arms being slidablymounted in the grooves, a tapered plate mounted in inclined slots ineach tongue and arm, a block slidably mounted on each plate and withinsaid slots, a threaded stem extending from said block and engaging theplate, and means for adjusting the block upon the plate.

In testimony whereof I affiX my signature in presence of two witnesses.
